Actually Birth by sleep is going to be on PSP, also that is shown at the end of KHII:Final Mix+. 358/2 is going to the DS. And Coded is what you said, cept it's how it's written in Jimmy's Journal from KHI.
Since KH3 is still in develoment, it is likely that it'll be for the PS3 because they want to improve the graphics and put it on a similar engine as the remake of FFVII that's also for the PS3. Or if we're lucky they might do a split and do a PS3, PS2, and Wii release thing.
Considering the price tag on the Ps3 they may leave as Psp, from what i've heard it's comming out on psp, who knows xD there's soo many theories
